. Beit knownthat I, CARL CHRISTIAN Lam SEN, residingat the town of l/Valkerton, in

the Province of Ontario, in the Dominion 5 of Canada, haveiinvented new and useful Improvements. in Structural Toys, of which.

the following is aspecification.

Theinvention relates to structural toys asdescribed in the present specification and shownin the accompanying drawings which form part of the same.

The inventionhas for its object the pro- .vision of means integral with ,component .parts of individual structural toys whereby such parts can be assembled to form the intended toy or model without involving the employment of nails, screws, nuts or analogous fastening means. In this manner structural'toys ofall descriptions such as working and othermodels of aeroplanes, vehicles and-windmills .etcetera, can be readily. assembled. and taken; apart at pleasure.-

.The invention consists essentially in the PIOViSlOIlIOf projections and corresponding apertures at the several junctures' of the component parts of .the model or toy; the invention beingycharacterized by the distinctive feature of extending certainprojections throughone or more of their connecting-parts and aflixing same together by the insertion: of a wedge pin throughan aperture in the projection outside of the; part to which it is aftixed thus holding the parts firmly together. I i

For the purpose of illustrating the ,invention, its. embodiment in the "model of an aeroplane is shown in the accompanying drawings; however, it will, of course, be

members. are I flat top and bottom members,

composed of flat side' memhers,j]as at .12,

readily understood that this is only a typishown detached for the purpose of indicatingthe manner of its connection. I

Figure 4 is a detail ofa rmldenextended to constitute a locking bar 7 Like numerals of reference designate corresponding parts throughout the'figures. of the drawings;

In the drawings the aeroplane body is constructed in three sections; a frontal section representing the bonnet which usually coversthe motor; an intermediate section forming the pilots quarters; and a tail section containing an observers seat.

The bonnet section comprises a pair. of flat converging side members, as at 1, havingintegral projecti ons as at 2, located at their corners. Contiguous with said side To as at 3 andtlikewise provided with pro. jections, ,as at 5, said .members being-dis cernible in Figure 2 of the drawings.

The members 1, 3 and 4 are attached" to a frontal plate 6 by insertion of their pro: jections in registering apertures 7 therein. Said members are similarly attached to a vertical strut 8 ,havingapertures, @Slitt 9, for this purpose. I v

Opposing =the..strut .8 is y a further strut 10 identical therewithin construction, and between the two is the-intermediate section of the body, .as at 11, which is composed, of flat members connected by interfitti-ng pro; jections and a'pertures'similar to thosedetailed in the description of the bonnet section. I y w The tailfsection of thetbody is likewise possessing integral frontal and rear projections, as at 13; which frontal projections enter apertures, as at 14, provided in the strut 10, whilst the rear projections are received in apertures 15 of a plate 16.

Contiguous with said side members are fiat top and bottom members, as'at 17, afflxed to the strut 10'and plate 16 by similar inter-v fitting projections and'apertures not shown; such members being discernible in Figure 3 of the drawings.

Extending rearwardly of the aeroplane body is a rudder 18 which is provided with an integral protracted bar l9 passing through the. plate 16 to and through the a pair of wheels 35.

frontal plate 6. The terminus of the bar 19 wedge-pinsin their apertures 26.

Each of. the strutsS and 10 are provided with integral-shoulders 27 situated-inelose proximity to their termini and in advance of said shoulders apertures 28 are provided receptive towedge-pin's.

Supported upon the upper termini of thesestruts is a wing 29 resting upon the shoulders 27 and secured by insertion of Wedge-pins in the apertures 28 of the termini. Similarly a wing 30 is connected to the lower termini of the struts and secured to same by further wedge-pins.

Connecting together the ends of said Wings are a pair of braces 31 having integral shoulders 32 abutting the respective Wings and having termini protruding through apertures therein and secured by Wedge-pins 33. i

The lower termini of the aforesaid strut 8 is extended beneath the wing 30 to carry an axle 34 which is attached in a similar manner'to that of otherp-arts hereinbeit'ore described, and upon'this axle are mounted It will be manifest from the foregoing description that whereas this invention is shown in its application to'the construction'of models or toys from parts already cut, stamped out, or otherwise manufactured, it will be readily understood that this Will,'without departing from the spiritand scope of the invention, also apply to a hobby wherein'the parts may be stamped or printed upon blanks in order that by fretwork such transverse members positioned at the head and tail of the body and between the adjacent ends of said sections so as to receive the respective projections of the said fiat members, a bar extending lengthwise of the body with its extremities entering further apertures provided in the transverse members located at the head and tail of the'body, a rudder integral with the said bar forming a shoulder to the rear of the tail-endtransverse member, and a Wedge-pin positioned in an apertureprovided in the portion of the bar protruding from the transverse member at the head-end of the body so as to cooperate with-the rudder in lockingthe component -parts of the body in their assembled positions. u

2. 111a toy aeroplane, a body having three aligned sections representing the bonnet, pilots quarters and tail of the aeroplane, each of said sections being composed of flat members, projections extending from the frontal and rear edges thereof, apertured transverse struts positioned between the adjacent ends of the sections so as to receive certain of the projections" of their flat members, an apertured plate positioned at the front of the bonnet section receiving the projections of its constituent members, a similar plate positioned at the rear of the tail section likewise fitted to its constituent members, a bar exending from'end' to end of the body entering further apertures provided in the said plates, arudder integral therewith formin a shoulder to the'rear of the tail plate, and a wedge-pin lodged in an end of the bar protruding from the frontal plate so as to cooperatewith saidrudder in locking'the component parts of the body in their assembled positions.
